Language is one of the most overlooked parts of customer service automation. A customer writing in Bangla who gets an English-only reply immediately feels like they're talking to a machine that wasn't built for them.
For businesses operating across India and Bangladesh, supporting Bangla, English, and Hindi isn't a nice-to-have — it's how most real conversations actually happen, often switching between languages in the same chat. A bot that can follow that switch, while staying disciplined about not drifting into languages it wasn't set up to handle well, keeps conversations feeling natural instead of scripted.
This is also a business decision, not just a technical one. Committing to a fixed set of supported languages — and being upfront with customers about it — is more trustworthy than an AI that attempts every language poorly.
